PHP实现新历与农历互相转换的方法

演示效果：

Array
(
    [0] => 2020
    [1] => 四月
    [2] => 十三
    [3] => 庚子
    [4] => 4
    [5] => 13
    [6] => 鼠
    [7] => 4
)

新建一个index.php文件

convertSolarToLunar($year,$month,$day);

echo '
';
print_r($month);
按照上面的示例，把index.php和lunar.php者两个文件放同一目录下就可以直接调用了

lunar.php类文件
lunarInfo[$year-$this->MIN_YEAR];
		if($year==$this->MIN_YEAR&&$monthgetLunarByBetween($year,$this->getDaysBetweenSolar($year,$month,$date,$yearData[1],$yearData[2]));
	}

	function convertSolarMonthToLunar($year,$month){
		$yearData=$this->lunarInfo[$year-$this->MIN_YEAR];
		if($year==$this->MIN_YEAR&&$monthisLeapYear($year)&& $month==2)$dd++;
		$lunar_ary=array();
		for ($i=1;$igetLunarByBetween($year,$this->getDaysBetweenSolar($year,$month,$i,$yearData[1],$yearData[2]));
			$array[]=$year.'-'.$month.'-'.$i;
			$lunar_ary[$i]=$array;
		}
		return $lunar_ary;
